Marinco 50A Shore Power: Setting the Standard at the Dock
When a large cruiser or liveaboard ties up for the night, the 50-amp shore power connection is the lifeline that runs the air conditioning, battery chargers, galley appliances, and every other onboard system. Marinco has been engineering that connection since 1972, and their 50A products represent the most complete and thoroughly refined lineup in the marine electrical industry. From cordsets and inlets to plugs, receptacles, and adapters, Marinco covers every component in the 50-amp circuit — at both the boat and the dock pedestal.
The PowerCord Plus: Marine-Grade Performance in Every Inch
Marinco's PowerCord Plus 50 Amp Cordset is a shore power cable designed for 50 amp, 125/250V AC service, built with heavy-duty, super-flexible marine-grade cable and corrosion-resistant, nickel-plated contacts. Every PowerCord Plus 50A cordset features an LED power indicator light, watertight molded plug and connector, contoured grip ends with a Thumbprint Locator for fast and easy connection, and the Marinco Easy Lock System Ring — a simple 1/8 twist of the ring that provides a fast, positive watertight connection. These cables are built with super-flexible 6-gauge tinned copper cable for maximum corrosion resistance.
The EEL Cordset: A Patented Leap Forward
For boaters who demand the fastest, most foolproof connection at the dock, Marinco developed the EEL (Easily Engaged Lock) ShorePower Cordset. The Marinco EEL 50A ShorePower Cordset delivers fast, secure 50-amp shore power with a patented jaw-clamp design that locks with one hand and creates a waterproof seal without a locking ring. Built for harsh marine environments, it features LED power indicators for safety and confidence at the dock. This innovation is particularly valuable in low-light or rough-weather docking situations, where fumbling with a traditional locking ring can be both frustrating and unsafe.
50A Inlets: Built to Last in Saltwater
The Marinco 50A Shore Power Inlet provides a secure, high-capacity 125/250V connection for reliable shore power delivery, built with a 316 stainless steel housing and a locking waterproof cap for durable, corrosion-resistant performance in demanding marine environments. A soft-touch cap stays open when upright for easy access, and a secure 4-wire locking connection ensures stable power transfer. Inlets are available in both 125V and 125/250V configurations to match the vessel's electrical system.
Plugs, Receptacles, and Adapters — A Complete 50A Ecosystem
Equipped with dust seals for contaminant-free operation, Marinco 50A male plugs and female connectors are available in 125V and 125/250V models. Featuring a corrosion-resistant reinforced nylon construction, Marinco 50A receptacles are available in a 125V 2-pole, 3-wire model and a 125/250V 3-pole, 4-wire model. Rounding out the lineup, Marinco's 50A adapters include straight adapters for dry locations, pigtail adapters for wet environments, and "Y" adapters for dual connections, giving boaters greater power hook-up flexibility.

Marinco 50A products are UL listed and ABYC compliant for safe, reliable dockside power delivery. Select models are backed by a 5-year limited warranty , reflecting the brand's confidence in its engineering and materials.
